REDUCING NOISE IN BALL VALVES
A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.
This application is a continuation of U.S. Ser. No. 17/119,650, filed on Dec. 11, 2020, and entitled “REDUCING NOISE IN BALL VALVES.” The content of this application is incorporated by reference herein in its entirety.
BACKGROUNDFlow controls play a role in many industrial facilities and systems. Ball valves are a type of flow control that find use in, for example, installations and networks that distribute fluids, like natural gas, vapor, water, or petroleum. One problem that subsists with these devices, though, is that the fluids may flow at rates high enough to generate vibration as it transits through the device. If left unchecked, the vibration results in loud noise, oftentimes in excess of acceptable safety levels. Many ball valves incorporate counter measures, including additional parts (or “trim”), that are meant to attenuate flow and suppress this noise.
SUMMARYThe subject matter of this disclosure relates to trim that suppresses noise in valves. Of particular interest are embodiments of a component (or “shoe”) that can integrate into structure of ball valves. As noted more below, certain implementations may be part of ball valves that are configured to throttle flow of fluids. These devices may have a rotatable closure member, or throttling ball, with a central opening or aperture. An end user can set this aperture in position relative to the fluid flow through the valve. This throttling position restricts flow and, often, introduces pressure loss or drop across the throttling ball. This localized pressure drop may cause vibration or noise problems. The shoe may have geometry that is useful to reduce errant flow that can cause vibrations, which is also a root cause of the noise. As an added benefit, the geometry may also allow the shoe to secure to the valve structure much better than with conventional fasteners (e.g., bolts). Welds around the periphery of the shoe avoid potential loosening of the shoe that may occur in operation in the field.
Reference is now made briefly to the accompanying drawings, in which:
Where applicable, like reference characters designate identical or corresponding components and units throughout the several views, which are not to scale unless otherwise indicated. The embodiments disclosed herein may include elements that appear in one or more of the several views or in combinations of the several views. Moreover, methods are exemplary only and may be modified by, for example, reordering, adding, removing, and/or altering the individual stages.
The drawings and any description herein use examples to disclose the invention. These examples include the best mode and enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. An element or function recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural of said elements or functions, unless such exclusion is explicitly recited. References to “one embodiment” or “one implementation” should not be interpreted as excluding the existence of additional embodiments or implementations that also incorporate the recited features.
DESCRIPTIONThe discussion now turns to describe features of the embodiments shown in drawings noted above. These embodiments are useful to throttle flow of fluids through ball-type valves. This feature suppresses noise that may emanate from the valves because of pressure drop at low (or lower) flow rates. As noted below, the embodiments may include a shoe that secures into a valve body with a rotatable ball resident therein. The geometry may also accommodate certain mounting hardware found in the valve, for example, plates (or “trunnions”) that support the rotatable ball in place in the valve body. Other embodiments are contemplated within the scope of this disclosure.
In view of the foregoing, the improvements herein help to suppress noise in ball valves. The embodiments address noise that occurs due to flow through the device. The embodiments also have geometry and features that permit use on plate trunnion-style ball valves. These features further permit welds to attach the embodiments in place on these devices. Notably, the same design for the shoe 100 may install onto pin trunnion-style ball valves, as well.
Examples appear below that include certain elements or clauses one or more of which may be combined with other elements and clauses to describe embodiments contemplated within the scope and spirit of this disclosure. The scope may include and contemplate other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
